2007-S Silver Proof

San Francisco struck 1,313,481 silver Kennedy half dollar proofs in 2007, the peak figure for the 2006 through 2020 silver Kennedy run and the high-water mark before a long mintage decline. The coin shipped in the 2007 Silver Proof Set alongside silver Roosevelt dimes, the five State Quarters of the year, and the first Presidential dollars and Sacagawea dollar, packaged in the Mint's purple-themed cardboard sleeve with a hard plastic lens and sold separately from the cupronickel Proof Set. Composition continues the silver-proof recipe in use since 1992: 90% silver and 10% copper at 12.50 grams, with an actual silver weight of 0.36169 troy ounces and a 30.6 millimeter diameter. The reeded edge shows uniform silver-white rather than the reddish cupronickel line that identifies the clad companion. The S mintmark sits above the date on the obverse, Gilroy Roberts's GR initials remain at the truncation of Kennedy's neck, and Frank Gasparro's FG sits to the right of the eagle's tail feathers on the heraldic reverse.

What collectors chase on this coin is Cameo and Deep Cameo contrast on 90% silver surfaces. Cameo, abbreviated CAM on slabs from PCGS, the Professional Coin Grading Service, and from NGC, Numismatic Guaranty Company, names the visual effect where the mirrored fields stay glassy black while the frosted devices read matte white under angled light. Deep Cameo, or DCAM, is the strongest version of that contrast. By 2007 the Mint's silver proof dies produced full cameo or deep cameo on essentially every strike, so the practical authentication concern is surface preservation rather than frost depth. Weight is the single cleanest physical separator from the clad companion: 12.50 grams against 11.34 grams, easily resolved on a basic gram scale. Diagnostics worth checking under good light include frost coverage on Kennedy's hair, the eagle's chest feathers, and the field mirror around the date and motto, where milky haze and hairlines from broken packaging are the typical PR70 disqualifiers.

As a collecting target the 2007-S silver proof is one of the most plentiful silver Kennedy proofs of the contemporary era in PR69 DCAM, with original Silver Proof Set packaging still widely available at modest cost. The price premium sits at PR70 DCAM, where small differences in surface preservation separate visually identical coins under loupe inspection. The 1.31 million figure is the high point of the modern silver-proof run; mintages drop to 994,000 in 2009, collapse under 400,000 in 2012, and bottom near 353,000 in 2016 before the composition switch rebounds 2019 slightly. Silver-proof specialists and type-set buyers acquire this coin for the 90% composition.
